A base station that controls carrier aggregation for a user equipment (UE) includes a memory configured to store weight factors for serving cells that are aggregated to provide wireless connectivity to the UE. The weight factors are determined based on characteristics of the serving cells. In some cases, the weight factors are determined based on frequencies of carriers used by the serving cells to provide the wireless connectivity to the UE. The base station also includes a processor configured to determine, based on the weight factors and a total weight assigned to the UE, weights for transmitting data to the UE via the serving cells. The base station further includes a transceiver configured to transmit data to the UE via the serving cells at priorities that are determined based on the weights for the serving cells.

In a cell where messages having a message type are sent without knowledge of radio frequency conditions for individual ones of user equipment within the cell, measured radio frequency conditions are accessed of multiple user equipment within the cell. Based on the measured radio frequency conditions, a minimum control channel coding rate is determined for a control channel for messages having the message type. Subsequent to a determination of the minimum control channel coding rate, transmission is caused toward all user equipment in the cell of the messages having the message type using the determined minimum control channel coding rate for the control channel. Methods, apparatus, computer programs, and program products are disclosed. The methods may be performed by a base station, self-organizing network server, or other apparatus.

A method of optimizing use of a plurality of high-rate packet data (HRPD) resources may include assigning one of the plurality of HRPD resources to each of a plurality of mobile stations that is coupled to a radio access network, where the one of the plurality of HRPD resources is used to establish one of a plurality of HRPD sessions between one of the plurality of mobile stations and a radio access network, and where each of the plurality of mobile stations is not using packet-switched data channel. Subsequently an additional mobile station wirelessly coupling to the radio access network and requesting an HRPD resource. A first HRPD resource is reassigned to the additional mobile station without notifying the first mobile station, where the first HRPD resource is used to establish an additional HRPD session between the additional mobile station and the radio access network. The first HRPD session and the additional HRPD session are simultaneously maintained using the first HRPD resource while the first mobile station is not using the PSD channel.

This method () adaptively sends control messages and a predetermined number of fast repeats of the control messages on the traffic channel of a mobile communication system. For a control message which has already been lost (), the system sends the control message again with a first number of fast repeats () if the traffic channel is operating at a full rate; and the system sends the control message with a second number of fast repeats if the traffic channel is operating at a subrate. The number of fast repeats is selectable. If the control message has not been previously sent and the traffic channel is operating at a subrate (), the system will send the control message with a third number of fast repeats ().

If successful time slots and data rates are found, a grant message is returned from the time slot manager () to the base station (). If insufficient time slots and data rate power are determined, a deny request message is transmitted to the base station ().

A method () schedules the utilization of the supplemental channel of a base station transceiver (-). This scheduling includes time slot assignment as well as data transfer rate per time slot. One method simply selects the next time slot with a maximum rate for the primary base station transceiver (). The method then selects the same time slot for each of the secondary links with the secondary base stations (). The data is then simply sent to each of the BTSs (-) for transmission to the mobile station (). In another alternative, a request is made for a supplemental channel usage for the primary link (). Then secondary links are selected for transmission to the mobile station () only if they provide additional diversity gain () and resources are available at the secondary link BTSs.

A mobile station typically determines whether to drop a communication link and/or a base transceiver station (BTS) based on a performance of an associated forward link. In order to avoid dropping a communication link that has a weak forward link but a strong reverse link, a communication system is provided that determines whether the reverse link is still good before determining to drop the communication link. In one embodiment, the communication system determines whether reverse link is still good based on a quality metric associated with the reverse link and quality metric(s) associated with one or more other reverse links that are in a soft-handoff mode with reverse link. In another embodiment, the communication system determines whether reverse link is still good by comparing a quality metric associated with the reverse link to a threshold.
